Replying to [comment:1 igloo]:
> This is a POSIX requirement for cc or ld, presumably?
Yes. See the c99 description:
http://pubs.opengroup.org/onlinepubs/9699919799/utilities/c99.html
Also, the general POSIX guidelines for options specify separating options
from arguments. This is not mandatory, only a guideline. I believe the
principle of least astonishment (or surprise) justifies this change in
GHCi (see http://www.faqs.org/docs/artu/ch11s01.html).
Looking at compiler/main/DynFlags.hs the patch may be as simple as
changing
{{{ , Flag "l" (AnySuffix (upd . addOptl))}}}
to
{{{ , Flag "l" (hasArg addOptl)}}}
which is the same code as Flag "optl". I haven't tested this.
